Thats not mine that is a general one, it needs to be based on your location and this information is usually on the electric bill

I have 9 tanks 3-75g that have some sort of electric on them all have lights and heaters, but not all have filters..some have 2 filter running and I can't say my electric is any higher but its hard to compare since I have had the tanks running for so long...lol

I have other smaller tanks but they don't have anything electric running on them

I also have to calculate the well since it uses electric to pump water
